Hardman and Law unpick the complex ways in which identity manifests itself across "several dimensions" identify three core facets of identity: the relationships we form with different groups online, the attributes we share about ourselves through our behavior, and the agents we use to access online services.
The blog goes on to map the complex interplay between these different manifestations, and how these three dimensions intersect to shape digital identity.
Exploring the interplay between relationships and attributes, for instance, can be used to answer the question: "Who knows what about me?", while looking at agents and attributes tells us: "Which proxy represents me in which contexts, and how?"
The authors conclude that discussions of digital identity need to acknowledge the full complexity of how we manifest identity online:
“…we should model identity in its full richness. Then we should automate away what’s unhelpful in a given context. Only then will we have an identity that’s intuitive, flexible, and robust.”
